CPM drop a lot since last month & I think adfly should add in more variety of advertising to attract new advertisers. Currently adfly only offer interstitial, banner (full top), pop ads for advertisers. It can actually add another 468x60 banner ad option & make use of the space on the Skip Ad bar (as shown in picture below). This will help attract advertisers with smaller budget to advertise on adfly & in return give more earning to adfly publishers.
